Document Summary
Random assignment: random assignment facilitates comparison in experiments by creating similar groups. It is a mechanical method; the assignment is automatic, and the researcher cannot make assignments on the basis of personal preference or the features of specific cases. Individual cases differ in thousands of ways, and the researcher cannot know which might be relevant: true matching soon becomes an impossible task. The language of experiments: experimental research has its own language or set of terms and concepts random assignment and independent and dependent variables. In experimental research, the cases or people used in research projects and on whom variables are measured are called the subjects. Debriefing is crucial when subjects have been deceived about some aspect of the experiment: examine data collected and make comparisons between different groups. Where appropriate, use statistics and graphs to determine whether or not the hypothesis is supported.
